SAFETY RAZOR AND BLADE Filed Jan. 19. 1942 fi w kazwsejag/ wa Patented Oct. 27, 1942 UNITED; STATES PATENT OFFICE I SAFETY RAZOR AND BLADE J ames Leslie Younghusband, Chicago, 111. Application January 19, 1942-, Serial No. 427,213

4Cla'ims. This invention relates to a safety razor and blade adapted to prevent blade rust.

Among the objects of my invention is to construct a razor blade of the safety type," so that.

when the razor is not in closed operating position, that the shaving edges of the bladewill be spaced from contact with the head and guard to prevent rusting. Another object is to provide a razor blade so constructed that it will, without extraneous attachments or parts, itself operate to space its shaving edges from the head and guard in non-shaving position, said blade also adapted to be compressed without unusual pressure between the guard and head in'closed posi-- 6 tion for'normal shaving efficiency. My invention also contemplates such other objects, ad-

vantages and capabilities as will later more fully I appear and which are inherently possessed by 2-2 of Fig. 1 showingv the construction in open position; Fig. 3is an end elevational view in open position; Fig. 4 is an end elevational viewv in closed shaving position and Figs, 5 and 6 are perspective views of different, blade embodiments. The usual safety razor has a head I0 having a depending screw threaded shank- I I, aguard I2 having an opening I3 adapted to receive. shank II when the razor is assembled, and a handle I4 having a screw threaded aperture I5 adapted to engage the screw threads of shank II.

In combination with the foregoing parts, I provide inthe embodiment shown in F-igs. 2 and 5, a blade 22 which has a flatbody portion 23 with spaced cuts 24 extending inwardly from the end or non-shaving edges 25 of the blade 22. Between the cuts 24 are spring portions 26 integrally connected with the body portion 23 by uncut neck portions 21.

Some of the neck portions 21 of spring portions 26 are bent upwardly to form upwardly bent spring portions 36 and other preferably adjacent spring portions 26 have their neck portions 21 bent downwardly to form downwardly bent spring portions 46.

Another embodiment of my blade 22 is shown in Fig. 6, wherein I provide fewer cuts 24 and spring portions 36 and 46.

front elevational view partly in section on line In use, when a blade 22 isplaced between head I0 and guard I2 and the handle I4 is turned until head I0 and guard I2 bring inward pressure against spring portions 36 and 46 so as to ,unbend said spring portions 36 and 46 and flatof the blade will acquire rust spots, resulting in early deterioration of the blade, and creating a plurality of rough, broken, jagged edges which are likely to tear and stab the shaver in the next operation, instead of giving the smooth out necessary for shaving.

When the ordinary razor is loosened, the blade moves against either the head or the guard and the rusting by wet contact continues.

The only way to prevent this with an ordinary razor is to disassemble the head, guard, blade and handle and dry with a cloth. This is annoying and dangerous.

With my blade, after shaving, disassembly and drying with a cloth are unnecessary. The handle is slightly turned so that spring portions 36 and 46 return toward their normal expanded positions; The ends of spring portion 36 bear upwardly againstthe head In and the ends of spring portion, 46 bear downwardly against the guard I2 and space the shaving edges 28 away from contact with the head and guard. While the shaving edges 28 of the blade 22 are held spaced in this position away from contact with the head II] and guard I2, the razor may be held under a hot Water tap, and the stream therefrom will remove the accumulated hair and soap from the razor. Excess water may be easily removed by shaking the razor. There is nothing to hold Water against the shaving edges 28. Evaporation will then promptly dry the edges before they rust. The life of blades and their maximum efficiency is increased.

Having thus described my invention, I claim:

1. A safety razor blade comprising a body portion having a plurality of positioning holes located on a substantially central axis, shaving edges and non-shaving end portions, said end portions having a plurality of spaced cuts extending inwardly from the margins of said end por- 5 tions to form resilient portions between said cuts,

some of said resilient portions bent upwardly from said body portion and some of said resilient portions bent downwardly from said body portion so that said resilient portions are normally expanded with recesses below and above said upwardly and downwardly bent resilient portions respectively, said resilient portions adapted upon receipt of pressure to be compressed into said recesses in substantially the same plane as said body portion, said resilient portions adapted upon the release of pressure to expand away from the plane of said body portion, said resilient portions characterized by their inner extents being short of said positioning holes and on different axes therefrom.

2. A safety razor blade comprising a body portion having a plurality of positioning holes on a substantially central axis, opposite shaving edges and opposite non-shaving end portions, each of said end portions having at each side three spaced cuts extending inwardly from the margins of said end portions to form pairs of resilient portions among each group of three spaced cuts, one member of each of said pairs of resilient portions bent forwardly from said body portion and the adjacent member of each of said pairs of resilient portions bent downwardly from said body portion so that said resilient portions are normally expanded with recesses below and above said upwardly and downwardly bent resilient portions respectively, said resilient portions adapted upon receipt of pressure to be compressed into said recesses in substantially the same plane as said body portion, said resilient portions adapted upon the release of pressure to expand away from the plane of said body portion, said resilient portions characterized by their inner extents being short of said positioning holes and on different axes therefrom.

3. A rust preventing razor construction comprising a blade, a head positioned adjacent the upper surface of said blade, a guard positioned adjacent the lower surface of said blade, said blade having a body portion with a plurality of positioning holes on a substantially central axis, opposite shaving edges and opposite non-shaving end portions, said end portions having a plurality of spaced cuts extending inwardly from the margins of said end portions and adjacent the corners of said blade to form resilient portions between said cuts, some of said resilient portions bent upwardly from said body portion and some of said resilient portions bent downwardly from said body portion so that said resilientportions are normally expanded with recesses below and above said upwardly and downwardly bent resilient portions respectively, said resilient portions characterized by their inner extents being short of said positioning holes and on different axes therefrom, a handle adapted to move said guard toward said head and compress said upwardly extending portions of said blade downwardly within said recesses therebelow and substantially flat against said head and said downwardly extending portions of said blade upwardly within said recesses thereabove and substantially flat against said guard, said handle also adapted to move said guard away from said head, said upwardly and downwardly extending portions of said blade then expanding and contacting the inner surfaces of said head and said guard respectively, and spacing said shaving edges including the corners of said blade away from contact with said head and said guard.

resilient portions among each group of three spaced cuts, one member of each of said pairs of resilient portions bent upwardly from said body portion and the adjacent member of each of said pairs of resilient portions bent downwardly from said body portion so that said resilient portions are normally expanded with recesses below and above said upwardly and downwardly bent resilient portions, respectively, said resilient portions characterized by their inner extents being short "of said positioning holes and on different axes therefrom, a handle adapted to move said guard toward said head and compress said upwardly extending portions of said blade downwardly within said recesses therebelow and substantially flat against said head and said downwardly ex-
